U.S. new-vehicle fuel economy hits 24.1 mpg, another record, in March *UPDATE

As gas prices rise, Americans continue to speak with their wallets.

New car fuel economy levels in the U.S. reached a record high for the third straight month in March, reflecting efforts by the American public to curb refueling spending by buying more hybrids and four-cylinder cars, according to the University of Michigan Transportation Research Institute (UMTRI).

March's new cars averaged 24.1 miles per gallon, up from 23.9 miles per gallon in February, UMTRI said. Overall, newly purchased 2012 model-year vehicles are averaging 23.4 miles per gallon, up from the 2011 model-year average of 22.5 mpg. Fuel-efficiency numbers are up 13 percent from 2008, when vehicles had an average fuel economy of 20.8 miles per gallon.

The fuel-economy figures reflect efforts by Americans to buy less thirsty vehicles to combat rising gas prices, which are up about 60 cents a gallon since the beginning of the year and are approaching the $4 level.

In March, both Toyota and General Motors set monthly U.S. sales records with their Prius hybrid and Chevrolet Volt extended-range plug-in vehicles, respectively. Other models experiencing a surge in sales included the Nissan Leaf battery-electric and Volkswagen's diesel models.

*UPDATE: Using its own metrics, TrueCar calculates the average fuel economy to be 23.4. See the release after the jump.
